| Question | Answer |
| define Evolution | change overtime |
| what do we have that shows the world has change and living things | antibiotic resistant bacteria/ volcanic islands |
| 5 evidence of evolution in life on earth | - fossil evidence -structural comparison -embryology comparison -molecular comparison -microevolution |
| -who came up with the scie. explan. for how evolution occurs? -when did he live? -Where did he travel? -What did he see? -What did he ask? -What was his book? | -Charles Darwin -!8 hundreds -world and galapogos -lot of living things/ diversity with similarities -How could so much occurred? -On The Origin Of Species |
| What is the theory called | Natural selection |
| What were his three influences? | -artificial selection -great teachers-geologist& economist -observation from voyage |
| Define Natural selection | survival and reproduction of the fittest/ pocket mice is an example |
| $ 4requirements for natural selection | - over production -variation -limit on population -survival and reproduction |
| define adaptation | feature that enable survival |
| Adaptions: 1. structural 2. behavioral 3. physiological | Define and Exam. -body parts- wings, claws -response to environment- hiding, dancing -body function- venom, digestion |
| *Define variation/diversity | slight differences in adaptations |
| *what creates new combinations and possible ones | meiosis, sex. reproduction, mutations |
| *How can diversity help with survival | the more variation in a gene pool the less likely of extinction or better chance to survive/diversity increases survival |
| what is a gene pool | collection of genes inn apopulation |
| give and example of microevolution | light + dark pocket mice |
| difine species | organisms that can mate & reproduce viable offspring / healthy offspring |
| 5 mechanisms that keep them from mixing | - location - time -behavior -anatomy(parts) -genetics |
| what is speciation | the evolution of new species |
| what is extintion | complete loss of species |
| are both still happening | yes |
| how are humans classified | homo sapiens / primates |
| what are some of our unique adaptions | - problem solving -opposable thumbs -flexible forelimbs and shoulders |
| are their species that have lived in earth that fir inbetween to modern humans and other primates | are their species that have lived in earth that fir inbetween to modern humans and other primates |
| how do we know | - fossils -hair - foot prints that are fossils |
| what are the names of some human ancestors | current homo sapians middel australopithicus last ardipithicus lucy and ardi |
